SPECIFICATION forming part of Letters Patent No. 398,520, dated February 26, 1889.

Application filed January 25, 1888. Serial No. 262,191. (No model.) Patentedin France January 14, 1888, No. 188,140; in Belgium l'anuary 20, 1888, No. 80,325 inViotOriaIebruary 28,1888,N0.5,652,3.ndinllew South WalesMarch 1, 1888,1lo. 520.

A520, dated March 1, 1888, and in Victoria, No.

5,652, dated February 28, 1888,) of which the following a speci iication.

VThis invention relates to that class of mechanism wherein the indication is given by means of a spark or other light showing the position of the moving portion of the indicator, the object being to limit the time during which such indication is visible.

In order that my invention may be clearly understood I have annexed drawinhereunto, and have marked the same with iigures and letters of reference corresponding with those in the following explanation thereof.

Figure 1 is an elevation showing a dial or circular indicator with my improvements applied to a weighing-machine, the casing of my automatic apparatus being in VVsection and separate from the rest of the machine. Fig. Qshows (enlargedlone position of the coin-box, hereinafter described. Fig. 3 shows the corresponding position of the mercury-connection,

hereinafter described, and drawn to a larger scale. Fig. 1L shows another' position, hereinafter described, of the said coin-bor. Figs. 5, 6, and 7 show different means for carrying out myinvention. Fig. 8 shows a modified detail, hereinafter described.

As the indicator is actuated by the machine to which it is applied in exactly the usual way, I have not illustrated any special mechanism, but have merely shown the platform a, upon which the person (or article) to be weighed stands, and the pillar l) for supporting the dial c. i

In the case illustrated on Fig. 1 I fix an opaque mask or disk, d, in front of the index or iinger, (shown dotted at 6,) so as to entirely conceal the same. If there is glass in front of the dial or scale c, this mask may be made by painting on the back of the glass. The

f and falls into a small box, m..

l linger e of the weighing-machine moves behind the mask d, so as to indicate the weight when any article or person is placed on the platform, but is not visible until an electric spark is caused to issue from the point thereof across or to the numeral opposite to which the linger stops. For this purpose the spindle f, which turns with the finger c, is in electric connection with one of the wires, g', in

disk, g, which revolves in mercury contained in ametal trough, g2, to which the wire g is connected.

The dial is provided with a ring of metal, 71 insulated from the shaft f and finger e, and this ring hA is placed in electric connection with the other Wire, 71,

There is a breach of continuity of the wire 1;', lcadin g to or from the battery K, so that the electric circuit is not complete, and although the presence of a weight on the platform a of the machine will be indicated by the movement of the index or finger e in the usual manner, yet, in consequence of the said finger e being behind the mask d, such movement will not be visible; but on the introduction of the proper coin into the apparatus the electric circuit will be completed, and a spark from the index or finger c to the point on the ring 7L opposite to the numeral on the dial or scale c lo which the index ornger cis pointing at that particular time, and this electric spark or sparks will thus indicate the weight wh ich has been ascertained by the mechanical portion of the machine in connection with the said finger e. In the case illustrated the coin is placed through a slit into a chute, l,

(Shown enlarged in perspective view at Fig. 2.) This box nl is supported by a cord, n., (or its equiva- 'lent,) passing over a pulley, o, 'and having a counterbalance-weigh t, p, attached to its other end, which is su ificiently heavy to raise the box m when empty and support it in the position shown in fulllines on Fig. 1. Then the coin falls into the box, it overcomes the counterbalance-weight p and cans-es the box to descend, being guided by the iixed Wires q or equivalent means. At the side of the box m there is a small perforated arm, fr',

or a succession of sparks will be given out n connection with a battery, K, by means of a IOO through which passes a oord, S, provided with a knot or button, S, to the lower end of which is attached a forked or bent piece of metal, t. (See Fig. 3.) As the box m descends, the arms or ends of this fork t descend into mercury contained in two glass tubes, t. The wires la from the battery K dip into or are otherwise in connection with the mercury, and thus the electric circuit is completed and a series of sparks is caused to pass from the end of the iinger or index e to the opposite point on the metal ring h, (orvice versa,) and thus indicate the numeral to which the finger e is pointing.

plunger, u, having an inclined upper surface and forming the bottom of the` box m, (see Fig. 4,) comes into contact with a lixed part of the apparatus, and causes the coin to be pushed up out of the box m, when it slides off into a suitable receptacle, mx. The box m, being thus lightened ofits load, is then drawn back by the counterbalance-weight p into Vits original position. As soon as the arm fr ar'- rives at the knot or button S on the cord S, it causes the same to lift the fork t out of the mercury, and thus disconnects the wires k and breaks the circuit, (see Figs. 2 and 3,) and the discharge of the electric sparks, and consequently the visible indication, will cease.

The coin may be introduced into the apparatus by means of a coin-slide such .as was patented by myself in the United States of America, dated October 4, yA. D. 1887, No. 371,145.

The wires 7i and g may be con necied to an electric lamp, if", inside the casing of the indicator, as shown at Fig. 5, and behind the finger or index e. The mask d is in this case transparent, and when a coin is placed in the apparatus the position of the linger or index e is visible'through the said mask. The box m may be made (as it descends with a coin in it) to release a balanced lever, S2, which actuates ya tap, S3, for turning on an increased quantity of vgas through a pipe, S4, to a jet, S5, xed in the casing of the indicator, as shown Vv'hen the box m arrives at its lowest point, as shown dotted on Fig. 1, a I

at Fig. 6; or the box m may remove a tul'Jular or other screen, p', covering a Vconstant light, l

p2, the screen p by preference forming the weight to counterbalance the said box m, as shown by Fig. 7 5 or the light may be removed by the box m from behind the screen.

The box ym may be provided with other means than the plunger u for rejecting the coin when it has reached its lowest position. For example, it may be provided with a hinged piece, a', tilted by the fixture u2, upon which it descends, as shown at Fig. 8, so as to turn out the said coin a3.

I do not herein claim any particular kind of light for illuminating my weighingma chine, for I have tiled separate applications therefor as follows: Serial No. 262,192, filed January 25, 1888, and Serial No. 262,162, led January. 27, 1888.

I claim as my invention-'-` 1. The combination, with a coin-box open at the top and movable in a verticaliplane, of a bottom for said box movable therein and a stop in its pat-h of .movement for engaging with the bottom and forcing the coin up out of the box.

2. The combination of a masked indicator, a light for illuminating the said indicator, a movable controller which causes the light to be displayed 'orfcut offja movable coin-box attached to and actuating said controllena movable bottom for said box, causing the removal of said coin when at the end of its path of movement, and means for restoring the box to its normal position.

3. In a weigh'ingmachine, the combination of an indicator and a mask for the same, with an electric lamp located behind the mask and in an electric circuit, a circuit-breaker in the circuit with said lamp, a moving coin-box, and a connection between the latter and the circuit-breaker, whereby the .light is controlled by the movement of the coin-box.

In testimony whereof I have signed my name to this specification in the presence "of two subscribing witnesses.
